Other info. - This plant
is sometimes confused with V. urticifolia L. but the
latter has flowers which are not as dense on the spikes and with corollas
which are typically white. V. urticifolia also has
much broader leaves than does V. hastata.
V. hastata
is a common plant and can bloom when quite small if mowed or cut frequently.
Steyermark lists three forms for
the species. Form hastata, pictured above, has the
typical blue-purple corolla. Form rosea Cheney, has
a rose-colored corolla and is rare. Form albiflora Moldenke,
has a white corolla and is also rare.
